Hello guys!
I accidentally connected a led without resistor in the esp32 vin and gnd pin. The led burned and now my esp32 is showing error while uploading code. "A fatal error occurred: MD5 of file does not match data in flash!
Failed uploading: uploading error: exit status 2".
the full error is given below

Re: A fatal error occurred: MD5 of file does not match data in flash!
What devboard do you use? Generally, there's a schottky diode between the USB 5V line and the rest of the devboard, to prevent backfeeding. Chances are that you damaged that diode and now the ESP32 doesn't get enough power anymore.
